I encounter this a lot as well.

The only online game that I play nowadays is League of Legends, mainly because I've been playing since Season 2 (meaning I've been playing that game for 10 years now) and I've got very used to it. I can just play without focusing too much, because I'm on autopilot, and I very rarely try really hard to win, at least not any more since I got some heart problems a few years ago for getting angry at stupid people too often and too much.

However, the amount of people I encounter that are simply brainded, not because of the way they play but because of their mentality and behavior, would make me go crazy if I would not put effort into remaining calm.

I went past wanting to give a quick and great reply to their stupid remarks, I just want to beat them with a baseball bat sometimes, especially when I play great and I have a score like 3/2 (3 kills, 2 deaths) against a much better opponent or someone who receives help from his teammates, and then some moron on my team having a score like 2/7 (2 kills, 7 deaths) starts calling me a retard or whatnot because I didn't play the way he think I should have.

Also, I hate metas in games. I want to have fun, not to micromanage my entire inventory, spells, characters, and income and spend 16+ hours a day playing just to be in the top 1%. It's sad that some of those who are in the top 1% think they've achieved something important and act as if they're somehow superior to you.

Gaming of any type is fun. The people in some games are not. That's why I mostly play single player games.
